  • Patent number: 7705098
    Abstract: Chemically crosslinked polycyclooctene having excellent shape recovery properties is prepared by ring-opening metathesis polymerization of cis-cyclooctene followed by chemical crosslinking. The crosslinked polycyclooctene can be shaped, the shape memorized, a new shape imparted with the original shape being recoverable by suitable temperature adjustment. The dependence of shape memory characteristics on degree of crosslinking was established. In addition to polycyclooctene, blends thereof with other materials such as SBR, EVA, polyurethane rubbers, and inorganic fillers can be utilized to provide chemically crosslinked products having excellent and tailored shape memory properties.

  • Patent number: 7524908
    Abstract: A copolymerized high polymer film includes plural organic polymers, as skeleton, and is manufactured by blowing more than two kinds of organic monomers of respectively specific structures, in a vapor phase condition, onto the surface of a heated substrate, through plasma being generated in a reaction chamber. As a result, manufacture of an organic high polymer film capable of further reducing the effective relative permittivity of organic polymer films as a whole can be achieved, and, at the same time, further improvement in mechanical strength of film as well as film forming speed can be achieved.
